ARCH SUPPORT.

Specification of Letters Patent. Paibgmted A g 22 1:922

Application filed November 26, 1920. Serial No. 426,596.

T 0 all whom may concern:

Be it known that 1:, Ptunonr Lnsrre, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Arch Supports, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in arch supports.

It is one of the objects of the present invention to provide an arch support more particularly adapted for the relief of breaking down of the arch of the foot, and to make the support readily adjustable for variation in the curvatures and to permit the gradual building up of the metatarsal arch of the foot to its normal height.

A further object of the invention is to provide an arch support formed in part of yielding and pliable material positioned in layers or laminations of decreasing area up wardly with the periphery of each withln that of the one below, the edges of the layers or laminae being skived or pared to form a smooth beveled arch supporting surface which when engaged bythe foot will cause the bones to assume their correct positions to maintain the foot arch.

A further object of the invention is to provide an arch support in which the metal part of the support is enclosed so that it will not contact with parts of the shoe or the foot.

'With the above and other objects in view the invention consists of the improved arch support and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views- Fig. 1 is a top view of the improved arch support, parts broken away to show interior construction Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1; and? Fig. 3 is an edge view of the base plate and one of the pads.

Referring to the drawin the numeral 5 indicates an insole which is formed of upper and lower pieces of leather 6 and 7 or other like material preferably sewed together alon one side and both ends by a line of stitcles 8 to form a pocket 2? provided with a side opening 10. The insole portion 5 is shaped to fit within a shoe and comprises rounded rear or heel portion 11, a medial arch supporting portion 12 and a forward thin edge 1 portion 13. Said heel portion properly positions the insole within the shoe with the front edge of the insole terminating a slight distance in advance of the arch of the foot.

VVithinthe pocket of the insole is removably positioned a metallic spring base plate 14 which is formed with an innerup curved instep portion 15 medially of its length to support the inner side portion of the arch of the foot. The base plate is also upwardly curved longitudinally of its length to form a resilient arc-h portion 15 extending under the entire arch of the foot.

Tn first starting to wear the support the resilient base plate may be inserted in the insole pocket to slightly raise the arch of the foot and as the patient becomes used to the support a felt pad member 17 is placed in the pocket above the base plate to further raise and correct the arch. The pad member 17 is approximately the same size as the base member and is comparatively thick medially of its inner edge adjacent the upcurved instep portion 15 of the base member and is skived or tapered from this inner portion 18 transversely to its outer edge 19 and its end edges 20 to prevent the formation of shoulders in the upper piece 6 of the insole.

The wearing of the padded insole will further elevate the arch of the foot and when the patient becomes used to the wearing of this thicker support and the foot arch has been corrected to this extent a second pad 21 is placed in the insole pocket above the first pad. The second pad is also thicker adjacent the inner portion of the arch and is skived off in the same manner, transversely and longitudinally, as the first padand is of less size to form a more gradual taper.

While only two pads are shown it is to be understood that any number desired may be inserted in the insole pocket and that each one will decrease in size upwardly and will have its front, rear and outer side edges skived or tapered to form a smooth upper surface. As the pads are of less length than the pocket they may be shifted forwardly or rearwa-rdly to adjust the insole to fit arches of different shapes.

From the foregoing description it will be seen that the arch support is of very simple construction and is Well adapted for the purpose described.

What I claim as my invention is:

1. An arch support, comprising a flexible insole member formed of an upper and a lower part connected together along its outer edge and both ends to form a pocket with an inner edge opening, a metallic spring base plate removably positioned Within said pocket and having an upcurved medial edge portion, and a pad member removably positioned within the pocket and above the base plate and having its front and rear and outer side edges skived outwardly.

2. An arch support, comprising a flexible insole member formed of an upper and alower part connected together along one side edge and both ends to form a pocket with a side edge opening, a metallic spring base plate removably positioned within the pocket and having an upcurved medial edge portion, and a plurality of pad members of graduated sizes insertable in said pocket, said pad members being comparatlvely thick on one side edge and tapering therefrom out- .wardlyto form opposite thin side and end edges.

3, An arch support, comprising a flexible insole member formed of an upper and a lower part connected together along its outer edge and one end to form a pocket with a side edge opening, a metallic spring base plate removably positioned Within the 7 pocket and having an upcurved medialiedge nature.
